IMPROVEMENT IN HEAT-RADIATORS.

Specification forming part of Letters Patent No.156,934, dated November 17, 1874; application led October 3, 1874.

To all whom it may concern:

Be it known that I, OWEN MARRIN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Heat-Radiators, of which the following is a specification:

Theinvention consists in providing the inner cone of the radiator with iiexible plates projecting from its base, and arran ged at suitable distances apart to regulate the size of the openings, through which the heated air, gases, and other products of combustion ascend in the ilue, as hereinafter described.

Figure l is a central vertical section of the heater, taken on the line .fr m of Fig. 2. Fig. 2 is a top View, with the upper part of the outer casing removed.

Similar letters ot' reference indicate corresponding parts.

This heater consists of an upper and a lower cone, A B, (having their bases joined together) which inclose an interior cone, C, which is attached to thejoint D, and nearly fills the upper portion B ofthe heater. This interior cone C is of less diameter than the outer casing, the circle E representing its base, but it is attached to the joint D by a series of lateral project-ions, F, which extend horizontally from the base E, between which projections are openings G, which allow the smoke and gaseous products of combustion to pass upward and around the outside of the inner cone C. These openings G may be diminished or increased in size by means of small liaps G,

which are bent downward from the inner side ot the circle or base E. The size of these openings will depend upon the draft, and in inakingthe heaters the aps may be adjusted according to the draft ofthe chimney. The lower portion of the heateris a chamber, H, in to which the smoke, Src., is discharged from the stove. At each end of the heater is a neck, I, which receives the stove-pipes J J, or the heater may be placed directly on the collar of the stove, as may be desired. Ordinarily it would be placed-say, one length of pipe` above the stove with pipe extending from its upper neck. There may be a number of these heaters connected with the pipe, arranged in any desired manner for heating chambers or other apartments.

The radiator is made of sheet metal. I do not claim a radiator formed of two or more cones; but

Having thus described my inventionl I claim as new and desire to secure by Letters Patent- In a heat-radiator, the combination with the outer cone B of the inner cone (l, having a supporting-rim provided with notches forming openings G, and with the exible tlaps or plates G for regulating the admission ot' the products of combustion to the space K, as shown and described.

OWEN MARRIN.
